ALM-12068 Abnormal ACS Resources of Manager

Alarm Description

HA checks the ACS resources of Manager every 80 seconds. This alarm is generated when HA detects that the ACS resources are abnormal for two consecutive times.

This alarm is cleared when HA detects that the ACS resources are normal.

Resource Type of ACS is Single-active. Active/standby will be triggered upon resource exceptions. When this alarm is generated, the active/standby switchover is complete and new ACS resources have been enabled on the new active Manager. In this case, this alarm is cleared. This alarm is used to notify users of the cause of the active/standby Manager switchover.

Impact on the System

Possible Causes

The ACS process is abnormal.

Handling Procedure

Check whether the ACS process is normal.

In the alarm list on FusionInsight Manager, locate the row that contains the alarm, and click to view the name of the host for which the alarm is generated.
Log in to the host for which the alarm is generated as user root.
Run the su - omm command and then sh ${BIGDATA_HOME}/om-server/OMS/workspace0/ha/module/hacom/script/status_ha.sh to check whether the status of the ACS resources managed by the HA is normal. In the single-node system, the ACS resource is in the normal state. In the dual-node system, the ACS resource is in the normal state on the active node and in the stopped state on the standby node.
- If yes, go to 6.
- If no, go to 4.
Run the vi ${BIGDATA_LOG_HOME}/omm/oms/ha/scriptlog/acs.log command to check whether the ACS resource log of HA contains the keyword ERROR. If yes, analyze the logs to locate the resource exception cause and fix the exception.
After 5 minutes, check whether the alarm is cleared.
- If yes, no further action is required.
- If no, go to 6.
